Before opening or modifying the AD agent configuration files, stop the AD agent service under Windows Services.

From the terminal, locate the OktaAgentService.exe.instances.config file for each AD agent server:

C:\Program Files (x86)\Okta\Okta AD Agent\OktaAgentService.exe.config

Open the 'OktaAgentService.exe.config' file in a suitable text editor program and then locate the following line:

<add key="PollingThreads" value="2" />

The default value is 2 and the valid range is 1 - 10. As an example to increase the number of polling threads to four, edit the line to look like this:

<add key="PollingThreads" value="4" />

Save the file.

Start the agent.

Once the change has been made, save the file and then start the Okta AD agent service again. You can verify that the setting has changed by opening the agent.log file at startup and observing the startup information towards the bottom of the file:

2017/07/21 06:06:22.167 Debug – TEST-SERVER-1(4) – PollingThreads: 4

Now the agent has four concurrent polling threads searching for actions to perform.
